Here we will read and write definitions and descriptions
Definitions
A definition is a rethorical pattern you use to conceptualize words. Definitions usually have a term to be defined, a general class word and a characteristic or characteristics.
Example A dog (term to be defined) is an animal (general class word) that barks has four legs and a tail. (characteristics)
Description
A description is a writing form used to create an impression of an object, person, place, event, process, mechanism, etc . You can describe people, objects, animals, plants, or you can also describe how an event happened, how a mechanism operates, etcetera.
In a description you find many adjectives which are the words that will characterize any thing you want to describe. Example 1:
In an equilateral triangle, all sides are of equal length. An equilateral triangle is also an equiangular polygon, i.e. all its internal angles are equal—namely, 60°; it is a regular polygon.
This description was taken from the following web page: http://en.wikipedia.org/wiki/Triangle Example 2:
A polygon that is not convex is called concave.[2] A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
It is possible to cut a concave polygon into a set of convex polygons
This description was taken from the following web page: http://en.wikipedia.org/wiki/Concave_polygon
Term to be defined: addition
The general class word: an operation or process
Characteristics: used for calculating the sum of two numbers or quantities
Area:
Term to be defined: area
The general class word: a geometrical measure
Characteristics: measure used to calculate the surface of a bidimensional or flat object
Cube:
Term to be defined: cube
the general class word: a prism
Characteristics: a six square faces polyhedron
Line:
Term to be defined: line
the general class word: a extent of lenght
characteristics: a continuous extent of lenght containing two or more points
Volume:
Term to be defined: volume
the general class word: a geometrical measure
characteristics: a measure of number of cubic units needed to fill the space inside an object
II. Using your own words, write 1 definition about any mathematical terms.
A Right angle: IS ninety degrees angle present in any right triangles.
III. In the text you will find when you click the link below, extract the first paragraph and please find all the characteristics of fractals and underline them. Also find the adjectives and circle them.Be careful ! ! ! __http://en.wikipedia.org/wiki/Fractal__
The underlineD parts are the characteristics of fractals, and the italic or cursive words are the adjetives.
Because they appear similar at all levels of magnification, fractals are often considered to be infinitely complex (in informal terms). Natural objects that are approximated by fractals to a degree include clouds, mountain ranges, lightning bolts, coastlines, snow flakes, various vegetables (cauliflower and broccoli), and animal coloration patterns. However, not all self-similar objects are fractals—for example, the real line (a straight Euclidean line) is formally self-similar but fails to have other fractal characteristics; for instance, it is regular enough to be described in Euclidean terms.
Images of fractals can be created using fractal-generating software. Images produced by such software are normally referred to as being fractals even if they do not have the above characteristics, such as when it is possible to zoom into a region of the fractal that does not exhibit any fractal properties. Also, these may include calculation or display artifacts which are not characteristics of true fractals.
1. There is a definition of fractals there. Please identify it and identify its components. Afractal (term to be defined) is "a rough or fragmentedgeometric shape(definition) that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole,(part of the characteristics)" a property called self-similarity.
2. There is a description there, please identify it and tell me how you found it. What helped you when locating it.
A fractal often has the following features:
It has a fine structure at arbitrarily small scales.
It is too irregular to be easily described in traditionalEuclidean geometric language.
The note that says (a fractal often has the following features) helped me to locate the description Good. What about the adjectives??
IV. Now write a description of any mathematical word or topic.
A Right angle: is a ninety degrees angle. It can also be described as the meassure of an arc in a circunference of one unit of radius. It can be also meassured in radians being pi/2.
As soon as you have all these ready, please paste it in your wiki.

The underlineD parts are the characteristics of fractals, and the italic or cursive words are the adjetives.
A fractal is "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole," a property called self-similarity. Roots of mathematically rigorous treatment of fractals can be traced back to functions studied by Karl Weierstrass, Georg Cantor and Felix Hausdorff in studying functions that were continuous but not differentiable; however, the term fractal was coined by Benoît Mandelbrot in 1975 and was derived from the Latin fractus meaning "broken" or "fractured." A mathematical fractal is based on an equation that undergoes iteration, a form of feedback based on recursion.[2[[http://en.wikipedia.org/wiki/Fractal#cite_note-patterns-1|]]]
A fractal often has the following features:[3[[http://en.wikipedia.org/wiki/Fractal#cite_note-2|]]]
- It has a fine structure at arbitrarily small scales.
- It is too irregular to be easily described in traditional Euclidean geometric language.
- It is self-similar (at least approximately or stochastically).
- It has a //Hausdorff// dimension which is greater than its topological dimension (although this requirement is not met by //space-filling// curves such as the Hilbert curve).[4[[http://en.wikipedia.org/wiki/Fractal#cite_note-3|]]]
- It has a simple and //recursive// definition.
Because they appear similar at all levels of magnification, fractals are often considered to be infinitely complex (in informal terms).
